I’m sure people would have said similar things when iPad was first released with the A4 I think we should wait and see before making pre judgements
Have you actually checked the differences between iOS and MacOS? Have you actually checked the differences in software complexity between iOS and Mac?
Have you actually looked at latest benchmarks between latest and greatest ARM chips versus x86 chips?
Becuase I have. Graviton v2 which is the fastest ARM chip on the planet is still losing on average to Rome. By over 50%.
The only place where ARM is good at this point is lightly threaded workloads, everywhere when you high scalability, high coherency, highly threaded workloads ARM CPUs choke like 15 year boy before its crush. Heck, in those lightly threaded workloads it even beats Intel and AMD.
WHICH IS WHY APPLE ON iOS ACHIEVES SUCH PERFORMANCE!
Give it anything highly threaded and it will be absolutely the same situation as other ARM chips.
